I wonder if it is usable in my case and how do I use it? build with CONFIG_XFS_RT=y, and see the mkfs man page for the -r option. Then mount with -o rtdev=/dev/blah And test the heck out of it, it doesn't get that much use. -Eric _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
